HELLO, I HAVE A QUESTION USING FOR A TCA9548
-----
I2C CONDITION
MASTER1 - IO LEVEL 3.3V
- CONNECT
- PIN 19,20 (SCL,SDA)
- PIN 24 (RESET) TO MASTER GPIO
MASTER2 - IO LEVEL 1.8V
- CONNECT
- PIN 1,2(SD0,SC0)
SLAVE1 - IO LEVEL 1.8V
- CONNECT
- PIN 1,2(SD0,SC0)
MASTER1, WHEN WRITE TO SLAVE1, MASTER2 GOING TO RESET, AND DONE , TCA9548 GOING TO TURN OFF & MASTER2 WRITE TO SLAVE1 START TO ANOTHER WRITE...
-----
SO MY QUESTION IS THAT, WHEN TCA9548 IS TURNED ON, WHY DOES IT RISE TO A HIGHER VALUE THAN 1.8V (MOVEV TO 2.0V)?
